My googling says android has bourne sh, which has $! normally.

If it is reading stdin, no problem. You can strace in the background, too, so the command is in the foreground and you can type:
Code:
$ strace -fvxs 99999 -o /tmp/this_trace.tr -p $$ & am start com.android.mail

I used the command as you mentioned except 99999 as it didnt accept the argument. Everything is fine , but the strace exits as soon as the application opens. Is there a way to contine running the strace even after the application opens

What does the log say as to why it stopped?

-s strsize Specify the maximum string size to print (the default is 32).
Note that filenames are not considered strings and are always printed in full.

I think strace command is being run for /bin/sh and '&' command is executing the second part of command by just starting the application. so basically its not stracing the app. two commands are indipendtly executing

Well, for all I know android strace has no -f, as docs are hard to come by.
